Fhygadeuott.] BRITISH ICHNEUMONS. 8l 



F. GravenJwrsti has not before been noticed in Britain, but Mr. E. A. 

 Butler has kindly given me a female, which was bred l)y Tuck from a nest 

 of Bo)nhus hnrlorum, at Tostock, in Suffolk, in iSyy ; and I swept a 

 specimen, in Tuddenham Fen, in Suffolk, at the end of August, 1902. 

 Dr. Capron, also, found it at Shere, in Surrey. It has only been noticed 

 in Sweden and (lermany on the Continent.

Head black, with the palpi red and mandibles immaculate ; frons finely 

 and closely punctate ; vertex broad, and not narrowed behind the eyes ; 

 cheeks broad with an impressed sulcus ; clypeus apically acutely bidentate, 

 obsoleteiy discreted with the basal foveae large. Antennae very slender, 

 filiform and piceous. Thora.x immaculate ; metathorax of $ short, of $ 

 coriaceous ; areae entire ; areola transverse, broader apically, emitting the 

 coslulae from behind its centre, of $ sub-reniform and centrally costate ; 

 petiolar area reaching beyond the centre, discreted, of $ transversely 

 rugose with apophyses distinct, and very small, circular spiracles. Scutcllum 

 black. Abdomen nitidulous, black, with segments two to five red and 

 the sixth and seventh apically white \ basal segment not carinate, of 9 

 gradually explanate, strongly nitidulous and obsoleteiy aciculate, of $ 

 coarsely rugose with the post-petiole quadrate and parallel-sided ; terebra 

 slightly shorter than half the abdomen. Legs red ; coxae excepting front 

 ones of $ beneath, trochanters, hind tarsi, apices of their tibiae and 

 also rarely of their femora, black. Wings somewhat clouded ; radix 

 stramineous, tegulae black ; areolet small and the nervellus antefurcal. 

 Length, 4-6 mm. 



P. fuina/or, var. 7, appears to differ only in having the central segment 

 black-marked. 



This is a very distinct species in the vertical conformation, frontal and 

 petiolar sculpture, slender antennae, immaculate tegulae and mandibles, 

 small areolet and broad, sulcate cheeks. 



It appears somewhat rarer with us than upon the Continent, where it 

 is found in August. Maldon, in Essex (Fitch) ; Land's End (ALircjuand) ; 

 Plym Bridge, early in May (Bignell). I have never found it before 

 August, and the female not before the last days of September and early 

 October, when it may sometimes be discovered at dusk, sitting on the 

 stems of yarrow, on warm evenings. In the day-time both sexes frequent 

 the flowers of Daucus caroiu, and the female, when alarmed, rarely attempts 

 flight, but falling to the ground, endeavours to escape by running swiftly 

 among grass stems. I have taken it at Westleton, Benacre Park, 

 Wherstead and Bentley Woods, in Suffolk, and in the Blean Woods, 

 in Kent ; and received it from Abingtr Hammer, Felden, Shere ; 

 Cirecnings, in Surrey; Scotton Common, near dainsborough and 

 Huntingficld, in Kent.
